4.3. Cleaning
4.3.1. Pre-cleaning
(1) Open cylinder valve(s) of the mounted compressed air cylinder(s) fully.
(2) Remove rough dirt from breathing apparatus with water hose. Here, we
recommend using a mild detergent.
(3) Close cylinder valve(s) and release air from apparatus with lung governed
demand valve.
4.3.2. Cleaning, Light Soiling
(1) Remove compressed air cylinder(s) ( Section 3.12).
(2) Clean compressed air breathing apparatus manually using a brush, damp
cloth or similar.
(3) Dry apparatus completely in a drying cabinet at max. 60 °C.
4.3.3. Cleaning, Heavy Soiling
In the event of heavy soiling the compressed air breathing apparatus
should be partially dismantled.
The number of lines depends upon the type of pneumatics being used.
(1) Remove compressed air cylinder(s) ( Section 3.12).
(2) Disconnect lung governed demand valve from medium pressure line.
(3) Open the line retainer and unbutton the shoulder padding if present.
The shoulder straps and hip belt of the compressed air breathing
apparatus are fastened in the back plate with metal buckles. To remove
the straps and the belt, you must pull the buckles up slightly, tilt them
and push them out of the slots in the back plate.
If a swivelling hip plate is fitted the belt are removed with the removal of
the hip plate.
(4) Open line tunnel and unbutton shoulder pads at the snap fasteners.
The lowest button of the line tunnel is a heavy duty, three side locking snap
fastener (“pull the dot”) that is designed to withstand extreme pressure on three
sides without unlocking. When pulled on the fourth side where there is an
indentation on the “pull the dot” button (back of tunnel), the fastener will release
instantly.
